If it is connected to WIFI,
Go to settings on your phone, go to connectivity, go to WiFi and then reset your password from there. If your Tablet asks you for a new password, then enter 12345 because that is the default WiFi password for all Android devices. After that, you can enter a new password and re-create your WiFi password.

Hope that helps!

I'm assuming you have already used iForgot etc to reset your password first or that you no longer have that email..
Go to settings, scroll down to itunes /App store.
Click on your apple ID. and you will get some options such as IForgot to send a new password etc. If you truly cannot get your password, then click Signout. Then you will be able to create a new one when you try to register, you may need to create a new email account if your apple id was linked to your old one. Your old apps that will not update, you can delete them by holding your finger on them till they wiggle and click the X. then redownload with your new ID. Hope this helps.
